Non‐parametric Estimation of Tail Dependence

Scandinavian Journal of Statistics, 2006
Abstract.  Dependencies between extreme events (extremal dependencies) are attracting an increasing attention in modern risk management. In practice, the concept of tail dependence represents the current standard to describe the amount of extremal dependence.

Tail-weighted dependence measures with limit being the tail dependence coefficient

Journal of Nonparametric Statistics, 2017
For bivariate continuous data, measures of monotonic dependence are based on the rank transformations of the two variables.

The simple econometrics of tail dependence

Economics Letters, 2011
The aim of this paper is to show that measures on tail dependence can be estimated in a convenient way by regression analysis. This yields the same estimates as the non-parametric method within the multivariate Extreme Value Theory framework. The advantage of the regression approach is contained by its straightforward extension to the estimation of ...

Limiting Tail Dependence Copulas

Communications in Statistics - Theory and Methods, 2009
The limiting lower-tail dependence copula (LLTDC) is defined as the copula of random variables which are right-truncated at thresholds tending to their left endpoints. This article shows LLTDCs are truncation-invariant and belong to the Ahmadi-Clayton family.

Mesomorphism dependence on heterocyclic tail

Molecular Crystals and Liquid Crystals, 2016
ABSTRACTA novel homologous series of liquid crystal materials containing a heterocyclic ring was synthesized with a view to understanding and establishing the relation between liquid crystal (LC) properties and a molecular structure; and with a view to curing skin-related diseases following biological activity studies.

Tail-dependence in stock-return pairs [PDF]

open access: possible, 2002
The empirical joint distribution of return-pairs on stock indices displays high tail-dependence in the lower tail and low tail-dependence in the upper tail. The presence of tail-dependence is not compatible with the assumption of (conditional) joint normality.
